Description

Portable Workpiece Dressing Gripper

technical field

The utility model relates to a workpiece clamping tool, especially a portable workpiece trimming holder, which is especially suitable for grinding and trimming small workpieces in field construction sites, and is convenient for construction.

Background technique

On the field construction site, during the installation of machinery and equipment, there are often some small bolts, flat plates and other workpieces that need to be ground and trimmed before they can be used. Due to their large volume and weight, the bench vise and clamp table used to clamp the workpiece are mostly installed in the machine repair workshop, far away from the site. Due to the frequent movement of the field construction stations, if the transportation takes a long time, a transport vehicle is also required. On-site construction personnel generally use pliers or hand vise as a clamping tool to clamp the workpiece with one hand, and use a grinder or file for grinding and finishing work with the other hand. One hand uses a grinder or a file for grinding and finishing work, which has poor stability and safety. When the hand shakes, it will cause injury accidents such as broken polishing sheets and wounding people or grinding fingers. If two people work together, the danger will be greater if the movements are not coordinated.

Contents of the invention

The purpose of this utility model is to provide a portable workpiece trimming holder, which provides clamping tools for grinding and trimming small workpieces in field construction sites, improves the work efficiency of grinding and trimming small workpieces, and facilitates on-site construction.

In order to achieve the above purpose, the technical solution of the utility model is: the portable workpiece trimming holder includes a base, a support vertical plate and a clamping body, the support vertical plate is fixed on the bottom plate, the upper part of the support vertical plate is welded with a positioning sleeve, and the clamping body It is inserted into the positioning sleeve and fixed by positioning bolts. One end of the clamping body is a cylindrical workpiece clamping sleeve, and the other end is a plate-shaped workpiece clamping platform.

The remarkable effects of the utility model are: the utility model provides clamping tools for grinding and trimming small workpieces in field construction sites, improves the work efficiency of grinding and trimming small workpieces, and facilitates on-site construction. The utility model has the characteristics of simple structure, convenient carrying, fast clamping, good stability, high safety, etc., and has good application effect.

Detailed ways

The utility model is described in detail below in conjunction with the accompanying drawings, not limiting the protection scope of the utility model. Referring to Figure 1 and Figure 2, the portable workpiece trimming gripper includes a base 1, a support vertical plate 3 and a clamping body, the upper part of the support vertical plate 3 is welded with a positioning sleeve 6, the support vertical plate 3 is fixed on the bottom plate 1, and the clamping body It is inserted into the positioning sleeve 6 and fixed by the positioning bolt 7. One end of the clamping body is a cylindrical workpiece clamping sleeve 4, and the other end is a plate-shaped workpiece clamping platform 11. The outer circle of the middle part of the clamping body is provided with a positioning groove, and the positioning bolt 7 is inserted into the groove through the screw hole on the positioning sleeve 6. The cylindrical workpiece clamping sleeve 4 at one end of the clamping body is a cylindrical body, and the cylinder wall is provided with The screw hole is equipped with a fixing bolt 5; the plate-shaped workpiece clamping platform 11 at the other end is a semicircle, and the upper pressing block 10 is installed by a compression bolt 9 above the plane. The center hole below of the cylindrical workpiece clamping sleeve 4 is connected with the positioning arc, the diameter of the center hole is greater than the diameter of the positioning arc, and the fixing bolt 5 is on a center line with the center hole and the positioning arc. The positioning arc is a semicircular hole, and the cylindrical workpiece is fixed in the center hole of the cylindrical workpiece clamping sleeve 4, which not only can clamp cylindrical workpieces with different diameters, but also the positioning arc is in line contact with the cylindrical workpiece, increasing the number of clamped workpieces. stability. The upper plane of the plate workpiece clamping platform 11 on the outside of the compression bolt 9 and the lower plane on the outside of the upper pressing block 10 are provided with locking teeth, and the upper pressing block 10 on the inner side of the pressing bolt 9 is also provided with a screw hole. Pry bolt 8 is housed in the hole. If you do not install the prying bolt 8, you can also use a pad pad with the same thickness as the plate-shaped workpiece to support under the inner side of the upper pressing block 10, so that the both sides of the pressing bolt 9 are equal in height, so that it can be clamped between the upper pressing block 10 and the plate-shaped workpiece. The plate-shaped workpiece between the workpiece clamping platform 11 teeth is stable. The base 1 is provided with a magnetic attraction fixing seat 2, and a magnetic attraction 12 is housed in the magnetic attraction fixing seat 2, and the screw rod of the magnetic attraction 12 passes through the mounting hole of the magnetic attraction fixing seat 2 and is fixed by bolts. The magnetic attraction 12 exposed on the lower end surface of the base 1 can easily fix the holder on the metal plate of the pump base or other facilities on site, and the operation is convenient.

During operation, the plate-shaped workpiece is placed between the upper pressing block 10 and the plate-shaped workpiece clamping platform 11 . After tightening the compression screw 9, tighten the prying jackscrew 8 to make the front end of the upper pressing block 10 produce a prying force, so that the plate-shaped workpiece is clamped more firmly.

Put the cylindrical workpiece into the center hole of the cylindrical workpiece clamping sleeve 4, screw the fixing bolt 5 into the screw hole of the cylindrical workpiece clamping sleeve 4, and the fixing bolt 5 presses the upper circle of the cylindrical workpiece, and the cylindrical workpiece The lower circle of the workpiece is in line contact with the two sides of the positioning arc, and the three-point contact workpiece has good stability.

Loosening the positioning bolt 7 can make the clamping body rotate 360°, and adjust the plate or cylindrical workpiece to a suitable position. After tightening the positioning bolt 7, the plate or cylindrical workpiece can be trimmed with tools such as a grinder.
